British paratroopers carrying out NATO drills were stopped and asked to show their passports as they parachuted onto a Swedish island this week.
Soldiers were carrying out exercises in Sweden as part of wider Swift Defense 25 NATO drills aimed at preparing for the possibility of global conflict.
Drills including seizing a 'Tactical Landing Zone' from Swedish defenders, landing planes and parachuting onto the strategic Baltic island of Gotland.
Dozens of troops from the British Parachute Regiment were seen dropping from a Royal Air Force Airbus A400M in stunning video shot on Tuesday.
But as they landed, it was straight to Swedish passport control, as Britain is outside of the Schengen Area.
